1. What is the primary purpose of using a double-blind procedure in a neuroscience experiment? A) To ensure that the data collected is unbiased. B) To speed up the research process. C) To reduce the cost of the experiment. D) To increase the placebo effect. Answer: A) To ensure that the data collected is unbiased. Rationale: A double-blind procedure means that neither the participants nor the experimenters know who is receiving a particular treatment. This is crucial to prevent bias in research results. 2. Which neuroimaging technique involves the use of magnetic fields and radio waves to create detailed images of the brain? A) EEG B) PET C) MRI D) CT Answer: C) MRI. Rationale: MRI, or Magnetic Resonance Imaging, uses magnetic fields and radio waves to generate detailed images of the brain and other parts of the body, which is essential for studying brain structure and function. 3. In the context of neuroscience research, what does the term 'neuroplasticity' refer to? A) The electrical conductivity of neurons. B) The ability of the nervous system to change and adapt. C) The rigid structure of the neural network. D) The degeneration of neural connections. Answer: B) The ability of the nervous system to change and adapt. Rationale: Neuroplasticity is the brain's ability to reorganize itself by forming new neural connections throughout life, which allows the neurons in the brain to compensate for injury and disease and to adjust their activities in response to new situations or changes in their environment. 4. Which method is commonly used to measure the electrical activity of the brain? A) fMRI B) CT scan
